| 2 | Efficacy of Danggui Buxue decoction(当归补血汤)on diabetic nephropathy-induced renal fibrosis in rats and possible mechanism显示文摘OBJECTIVE:To observe the efficacy of Danggui Buxue decoction(当归补血汤,DBD) on diabetic nephropathyinduced renal fibrosis in rats,and to study the possible mechanism.METHODS:Sixty male Goto Kakizaki(GK) rats were randomly assigned to the model group,gliquidone group,astragaloside Ⅳ group,and high-,medium-and lowdoses DBD groups.After 8 weeks,changes in body weight,blood glucose,serum creatinine,serum urea nitrogen,and total cholesterol were observed.Changes in transforming growth factor-β1(TGF-β1),Smad3,and Smad5 pathways and the expression of the fibrosisrelated proteins collagen Ⅳ(col Ⅳ),α-smooth muscle actin(α-SMA),and vimentin were assessed.The degree of renal fibrosis was observed by immunohistochemistry and Mason staining.The expression of interleukin 6(IL-6),interleukin 10(IL-10),tumor necrosis factor(TNF-α),and C-reactive protein(CRP) in the kidneys was assessed using enzyme linked immunosorbent assay.RESULTS:Our experiments showed that DBD effectively reduced blood glucose,blood urea nitrogen,and creatinine levels after 8 weeks of administration,improved renal function in diabetic rats,alleviated renal fibrosis,and reduced the renal tissue levels of IL-6,IL-10,TNF-α,and CRP.Furthermore,DBD decreased the expression of TGF-β1,Smad3,col IV,α-SMA,and vimentin in renal tissues and increased the expression of Smad5.CONCLUSIONS:DBD ameliorates diabetic renal interstitial fibrosis by modulating the TGF-β1/Smads pathway. | ZHAO Ye WANG Xian GU Ling LI Zihang ZHU Jingtian WANG Wenkai ZHANG Liang XUE Mei | 2023 | Journal of Traditional Chinese Medicine2023，43，3： | 2 |
| 3 | Bismuth-Based Free-Standing Electrodes for Ambient-Condition Ammonia Production in Neutral Media显示文摘Electrocatalytic nitrogen reduction reaction is a carbon-free and energy-saving strategy for efficient synthesis of ammonia under ambient conditions.Here,we report the synthesis of nanosized Bi2O3 particles grown on functionalized exfoliated graphene(Bi2O3/FEG)via a facile electrochemical deposition method.The obtained free-standing Bi2O3/FEG achieves a high Faradaic efficiency of 11.2%and a large NH3 yield of 4.21±0.14μgNH3 h^-1 cm^-2 at-0.5 V versus reversible hydrogen electrode in 0.1 M Na2SO4,better than that in the strong acidic and basic media.Benefiting from its strong interaction of Bi 6p band with the N2p orbitals,binder-free characteristic,and facile electron transfer,Bi2O3/FEG achieves superior catalytic performance and excellent long-term stability as compared with most of the previous reported catalysts.This study is significant to design low-cost,high-efficient Bi-based electrocatalysts for electrochemical ammonia synthesis. | Ying Sun Zizhao Deng Xi‑Ming Song Hui Li Zihang Huang Qin Zhao Daming Feng Wei Zhang Zhaoqing Liu Tianyi Ma | 2020 | Nano-Micro Letters2020，12，10： | 2 |
| 4 | Ultrathin,flexible,and oxidation-resistant MXene/graphene porous films for efficient electromagnetic interference shielding显示文摘Designing and fabricating efficient electromagnetic interference(EMI)shielding materials becomes a significant and urgent concern.Hence,a novel ultrathin,flexible,and oxidation-resistant MXene-based graphene(M-rGX)porous film is successfully fabricated by electrostatic self-assembly between MXene and graphene oxide(GO)nanosheets,and subsequently thermal annealing under hydrogen-argon atmosphere.The rapid breakaway of functional groups on GO and MXene sheets induces formation of porous conductive network in film,thereby facilitating efficient shielding for incident electromagnetic waves.The optimal absolute shielding effectiveness(SSE/t)value of 76,422 dB·cm2·g−1 can be achieved at a thinner thickness of 15μm.More importantly,the effective removal of functional groups on MXene conspicuously improves the oxidation resistance of the film,endowing it with an excellent durability(12 months)in EMI shielding performance. | Xinwei Tang Jiangtao Luo Zhiwei Hu Shijie Lu Xiaoyi Liu Shuangshuang Li Xu Zhao Zihang Zhang Qianqian Lan Piming Ma Zicheng Wang Tianxi Liu | 2023 | Nano Research2023，16，1： | 1 |

| 6 | Adaptive transmit beamspace optimization design based on RD-log-FDA radar显示文摘Because of the range-angle dependency in random log frequency diverse array(RD-log-FDA) radar, a method for designing beamspace transformation matrix in angle and range based on the receive signal has been proposed.It is demonstrated that the designed beamspace transformation matrix basically meets the requirements of beam gain.However, there are some problems in the transformation matrix designed, such as unstable beam gain and high sidelobe.Hence, we propose an optimization method by adjusting array element spacing and random number in frequency offset to get the optimum beam gain.Therefore, particle swarm optimization(PSO) is used to find the optimal solution.The beam gain comparison before and after the optimization is obtained by simulation, and the results show that the optimized array after beamspace preprocessing has more stable beam gain, lower sidelobe, and higher resolution in parameter estimation.In conclusion, the RD-log-FDA is capable of forming desired beam gain in angle and distance through beamspace preprocessing, and suppressing interference signals in other areas. | DING Zihang XIE Junwei LI Zhengjie | 2022 | Journal of Systems Engineering and Electronics2022，33，1： | 1 |
| 7 | Anti-oxidative effect of zinc in human umbilical cord mesenchymal stem cells显示文摘Human umbilical cord mesenchymal stem cells(HUC-MSCs)are pluripotent and functional in many biological processes,by which releasing secretary factors to promote the self-repairing of damaged tissue or developing into functional cell at local organ.However,there is a high risk that oxidative stress would reduce the pluripotency and factor-secretion during the preparation and transplantation.Therefore,reducing oxidative stress is expected to improve the efficacy of HUC-MSCs therapy.Zinc[Zn] is an essential trace element which involves in the resistance of oxidative stress.To investigate Zn-regulated signaling pathways,we have profiled the gene expression at transcriptome level in primary HUC-MSCs treated with zinc sulfate,followed with GO and KEGG gene enrichment analysis.Zn treatment improved signal pathways for mineral absorption,cell growth,and cell death.Zn deficiency was mimicked by TPEN administration,which suppressed cell proliferation and reduced the expression of HUC-MSCs surface stem cell markers CD73,CD90 and CD105 by flow cytometry.Nuclear factor erythrocyte 2 related factor 2(Nrf2)plays an important role in antioxidant biological processes.In vitro treatment of Zn significantly increased Nrf2 and Sirt3 expression at gene level and protein level respectively.Zn supplementation inhibited TPEN-induced failure of cell survival and reversed the reduction of Nrf2 and Sirt3 expression,which further reduced the production of ROS.Zn successfully presented its antioxidation effect by activating Nrf2/Sirt3 signaling pathway in HUC-MSCs.Zn supplementation may improve the efficacy of HUC-MSCs therapy with reduced oxidative stress. | Xiaodan Lu Yifan Lin Xiuying Lin Qiang Zhang Zihang Wang Xuguang Mi Ruobing Wang Xiaofang Zhang Xu Luan Yan Liu Bing Li YanTan Yanqiu Fang | 2021 | Biophysics Reports2021，7，2： | 0 |
| 8 | Multi-timescale Energy Sharing with Grid-BESS Capacity Rental Considering Uncertainties显示文摘The growing number of distributed energy resources(DERs)in distribution networks brings new opportunities for local energy sharing.This paper proposes a multi-timescale en-ergy sharing approach among DER aggregators and distribution system operators(DSOs)considering grid-battery energy storage system(BESS)capacity rental and network operations.An energy sharing coordinator is created to manage the energy sharing with price determination.In an hour-ahead stage,the buying/selling energy and required grid-BESS rental capacity are optimally determined by the aggregators while the network operation is robustly considered by the DSO.In addition to renewable generation and loads,the power exchanges of the aggregators are treated as uncertainties.Then during each hour,15-min-ahead energy transaction and controllable DERs are optimized to track uncertainty realization.The uncertainties in the aggregators and the DSO are addressed by stochastic and robust optimization methods,respectively.To efficiently solve the proposed energy sharing problem,a distributed solution algorithm with step length control and step reduction techniques is developed.The simulation results verify the high efficiency of the proposed energy sharing approach.Index Terms-Battery capacity rental,distributed solution algorithm,energy sharing,optimization,uncertainty. | Bo Wang Cuo Zhang Chaojie Li Xiangjing Su Zihang Qiu Zhao Yang Dong | 2023 | CSEE Journal of Power and Energy Systems2023，9，4： | 0 |

| 11 | SETD2 mediates immunotherapy and radiotherapy efficacy via regulating DNA damage responses and genomic stability in lung adenocarcinoma显示文摘SETD2 is the main transferase for the trimethylation of histone H3 at lysine 36 (H3K36me3) in mammals. SETD2 plays important role in repairing DNA double strand breaks and maintaining chromatin integrity.1 In renal carcinoma, SETD2 deficiency caused DNA replication fork instability and DNA damage.2 The absence of SETD2 was also reported to have strong tumor-promoting effects in lung adenocarcinomas (LUAD).3 However, the other roles of SETD2 remain poorly understood in LUAD. In this study, we utilized comprehensive omics-data analysis to determine that SETD2 was associated with DNA damage and immune-related signals in LUAD. SETD2 knockdown induced DNA damage and cGAS activation in LUAD cells, and reduced the number of cells at the G1 phase. Moreover, SETD2 deficiency was conducive to mutation burden, immune cell infiltration, and immunotherapy responses. High SETD2 expression was associated with high radiocurability. These findings suggest that SETD2 may be a promising biomarker of therapeutic responses for LUAD patients, and offer novel insights into immunotherapy and radiotherapy. | Zihang Zeng Yanping Gao Jiali Li Jianguo Zhang Yangyi Li Fajian He Zhengrong Huang Linzhi Han Yan Gong Conghua Xie | 2023 | Genes & Diseases2023，10，2： | 0 |

| 13 | Charging-rate-based Battery Energy Storage System in Wind Farm and Battery Storage Cooperation Bidding Problem显示文摘Wind power has been proven to have the ability to participate in the frequency modulation(FM)market.Using batteries to improve wind power stability can better aid wind farms participating in the FM market.Battery energy storage system(BESS)has a promising future in applying regulation and load management in the power grid.For regulation services,normally,the regulation power prediction is estimated based on the required maximum regulation capacity;the power needed for the specific regulation service is unknown to the BESS owner.However,this information is needed in the regulation model when formulating the linearised BESS model with a constraint on the state of charge(SoC).This compromises the accuracy of the model greatly when it is applied for regulation service.Moreover,different control strategies can be employed by BESS.However,the current depth of discharge(DoD)based models have difficulties in being used in a linearization problem.Due to the consideration of the control strategy,the model becomes highly nonlinear and cannot be solved.In this paper,a charging rate(C-rate)based model is introduced,which can consider different control strategies of a BESS for cooperation with wind farms to participate in wind farm estimation error compensation,load management,energy bid,and regulation bid.First,the limitation of conventional BESS models are listed,and a new C-rate-based model is introduced.Then the C-rate-based BESS model is adopted in a wind farm and BESS cooperation scheme.Finally,experimental studies are carried out,and the DoD model and C-rate model optimization results are compared to prove the rationality of the C-rate model. | Zihang Qiu Wang Zhang Shuai Lu Chaojie Li Jingbo Wang Ke Meng Zhaoyang Dong | 2022 | CSEE Journal of Power and Energy Systems2022，8，3： | 0 |
